Configured namespace map entry overwritten in AegisJSONProvider
---------------------------------------------------------------

                 Key: CXF-3704
                 URL: https://issues.apache.org/jira/browse/CXF-3704
             Project: CXF
          Issue Type: Bug
          Components: Aegis Databinding
    Affects Versions: 2.4
            Reporter: James Phillpotts


I have a jaxrs service configured as follows:

{code:xml}
<util:map id="jsonNamespaceMap" map-class="java.util.Hashtable">
        <entry key="http://acme.com/aegis/customtypes"; value="t"/>
        <entry key="http://acme.com/v1/activities"; value="a"/>
        <entry key="http://model.v1.acme.com"; value="m"/>
</util:map>     

<jaxrs:server id="restServer" address="/rest">
        <jaxrs:serviceBeans>
                <ref bean="bookstoreService" />
        </jaxrs:serviceBeans>
        <jaxrs:providers>
                <bean class="org.apache.cxf.jaxrs.provider.AegisJSONProvider">
                        <property name="namespaceMap" ref="jsonNamespaceMap"/>
                </bean>
        </jaxrs:providers>
</jaxrs:server>
{code}

I then have a JSON payload for my service request:

{code:javascript}
{
  "m.details": {
    "m.date": "2011-08-05",
    "m.updates": [ 
      {
        "a.value": {
          "t.string": {
            "t.name": "My String",
            "t.value": "myValue"
          }
        }
      }
    ]
  }
}
{code}

However, the object parameter to the service method is not correctly populated 
with the value of {{date}}, or {{updates}}, and the logs contain messages such 
as:

{noformat}
WARNING: xsi:type absent, and no type available for m.date
{noformat}

A bit of digging around, and it seems to me the problem is at line 142 of 
AegisJSONProvider (and yes, I dislike the namespace map concept as much as the 
person that added comments at line 140 of AegisJSONProvider!):

{code:java}
namespaceMap.put(typeToRead.getSchemaType().getNamespaceURI(), "ns1");
{code}

I believe that {{put}} here should be switched to {{putIfAbsent}} - what is 
happening is that on initialisation, the namespace map correctly contains the 3 
entries as per the spring config, but when the message is processed, 
{{typeToRead}} is not null, and the configured namespace prefix, {{m}}is 
overwritten with {{ns1}}.
